SARAH EMELINE BOWSER, OF MUFF, PENNSYLVANIA.

VIOLIN-BOW.

SPECIFICATION forming part of Letters Patent No. 613,897, dated November 8, 1898.

Application filed December 31, 1897. Serial No. 665,012. (No model.)

To aZZ whom it may concern:

Be it known that I, SARAH EMELINE BOWSER, residing at Muff, in the county of Armstrong and State of Pennsylvania, have invented a new and useful Violin-Bow, of which the following is a specification.

This invention relates to improvements in violin-bows; and the object thereof is to provide a folding bow which may be quickly and readily folded to convenient size when not in use, so as to enable a smaller violin-case to be used than is now required to accommodate the ordinary bow.

With the above object in view the invention consists of a bow having the body thereof formed in sections, said sections having their meeting ends hinged together and formed with a shouldered lap-joint, the sections being also screw-threaded to receive a screwthreaded sleeve which is adapted to hold said sections in alinement when it is desired to use the bow.

The invention further consists in the improved construction, arrangement, and combination of parts hereinafter fully described and afterward specifically pointed out in the claims.

In order to enable others skilled in the art to which myinvention most nearly appertains to make and use the same, I will now proceed to describe its construction and operation, having reference to the accompanying drawings, forming part of this specification, in which- Figure 1 is an elevation of a violin-bow constructed in accordance with my invention. Fig. 2 is a similar view showing the same folded. Fig. 3 is an enlarged vertical longitudinal sectional View of Fig. 1. Fig. 4 is an enlarged view of the body of the bow, show-- ing the same in elevation, with the sleeve removed from the joint and the sections slightly separated.

Like letters of reference mark the same parts wherever they occur in the various figures of the drawings.

The body of the bow is composed of the sections A and B, section B being somewhat longer than section A, said sections being hinged together at C and having their meeting ends reduced, as illustrated at D, said reduced ends adapted to overlap when the bowsections are in alinement, thus forming a shouldered lap-joint. The sections are screwthreaded at their meeting ends, as illustrated at E, the screw-threads on section A eXtend= ing rearward from the end thereof a greater distance than those upon section B to receive the sleeve F, which is interiorly screwthreaded and provided with the annular exterior enlargement G, which is milled, so as to be readily engaged by the fingers for rotating the sleeve. This sleeve is adapted to be adjusted to cover the joint, as illustrated in Fig. 3, and thus hold the sections in alinement.

WVhen it is desired to fold the bow, all that is necessaryis to rotate the sleeve to uncover the joint, when the smaller section A may be swung inward against the under side of sec tion 13, as illustrated in Fig. 2. Thus the bow is folded to convenient length and a smaller violin-casing may be used than is now the case with the ordinary bow. The ordinary violin-case is made considerably longer than the violin in order to accommodate the bow. With my improved folding bow the case may be shortened, and thus be more convenient to carry.

WVhile I have illustrated and described the best means now known to me for carrying out my invention, I do not wish to be understood as restricting myself to the exact details of construction shown and described, but hold that any slight changes or variations, such as might suggest themselves to the ordinary inechanic, will properly fall within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A violin-bow having the body thereof formed of sections hinged together,and means for holding said sections'in alinement, substantially as described.

2. A violin-bow having the body thereof formed of sections hinged together and having their meeting ends so formed as to provide a shouldered lap-joint when the sections are in alinement, and means for holding said sections in alinement, substantially as described.

8. A violin-bow having the body thereof sections in aiinement, substantially as deformed of sections hinged together and havscribed. ing a shouldered 1a joint at their meeting 7 ends, said meeting? ends being exterioriy SARAH EMELINE LOXVSER' 5 threaded, and an interiorly-threaded sleeve Vitnesses:

carried by one of said sections and adapted J. H. PAINTER, to be moved to cover the joint and hold the JOSEPH T. MCAFOOSE.
